2020-07-05 20:22:18 +0200 | asked a question | How do I solve cos(2*t)==sin(t) I tried solving
I got
But this shouldn't be the value. I know from the graphs that the value is numeric. I have also noticed that sagemath is not good for solving trig identities. Is this true? |
2020-07-05 03:32:28 +0200 | asked a question | why doesn't sage solve ln I have a simple equation to solve
The actual value should be $x > e^2$ but sagemath gives
How do I get actual value? |

2020-07-04 19:49:23 +0200 | asked a question | why sagemath returns 2 solution instead of one when I run the expression
It returns
But I'm hoping that it would return
How do I get my expected value? |
2020-07-04 19:34:36 +0200 | asked a question | how do I test if a function is continuous Is there a way to test programmatically if a function is continuous? e.g $f(x) = \frac{1}{x} $ I'm looking for a function is_continuous(f) = False |

2020-06-28 02:19:32 +0200 | asked a question | How do I differentiate an implicit function in sagemath? I'm trying to differentiate an implicit expression $x e^{y} = x -y$ This is my sagemath code Sagemath Answer is $\left( x, y \right) \ {\mapsto} \ \left(e^{y} - 1,\,x e^{y} + 1\right)$ But the actual answer is $\frac{1 - e^{y}}{x e^{y} + 1}$ How do I get the actual answer using sagemath? |
